Reset history position when leaving command line (#953)
Previously the history position was only reset when executing the
history prev/next command in normal mode, so it was not reset if you
entered command-line mode then started moving through the history.

Fix minor incsearch weirdness (#944)
This fixes an issue where if you stared a search then deleted the search
text (with e.g. backspace) it would perform a search for the empty
string and move the selection to the next file.

Fix a few completion bugs and add a few small features (#934)
* Fix some multibyte character completion bugs

- matchLongest now operates on runes instead of bytes so we don't
  complete part of a multibyte character.
- Fix some places that mixed string and rune slice indices.

* Fix wrong menu completion for subdirectories

When selecting a menu completion for a file in a subdirectory, the
entire filename would be appended to the command line, even if you had
already typed part of it.

* Escape file completions in menu completion

* Minor refactors and typo fixes

* Fix cmd-menu-complete-back bug

The first use of cmd-menu-complete-back after opening the completion
menu was incorrectly selecting the before-last completion instead of the
last completion.

* Allow completing broken symlinks

Also skip files with stat errors instead of returning.

* Add command to accept current menu selection

This is useful when completing filenames. For example

    cmap <c-y> :cmd-menu-accept; cmd-menu-complete

can be used to accept the selected directory completion, then complete
files in the directory.

* Complete command names for map and cmap

Documentation fixes and updates (#933)
- Document history option
- Use $() command substitution syntax because backticks are replaced
  with quotes in gen/docstring.sh
- Movement commands no longer close the search prompt (85aa3b9)
- Use the -L flag of the file command instead of readlink

.SH SEARCHING FILES
There are two mechanisms implemented in lf to search a file in the current directory. Searching is the traditional method to move the selection to a file matching a given pattern. Finding is an alternative way to search for a pattern possibly using fewer keystrokes.
.PP
Searching mechanism is implemented with commands 'search' (default '/'), 'search-back' (default '?'), 'search-next' (default 'n'), and 'search-prev' (default 'N'). You can enable 'globsearch' option to match with a glob pattern. Globbing supports '*' to match any sequence, '?' to match any character, and '[...]' or '[^...] to match character sets or ranges. You can enable 'incsearch' option to jump to the current match at each keystroke while typing. In this mode, you can either use 'cmd-enter' to accept the search or use 'cmd-escape' to cancel the search. Alternatively, you can also map some other commands with 'cmap' to accept the search and execute the command immediately afterwards. Possible candidates are 'up', 'down' and their variants, 'top', 'bottom', 'updir', and 'open' commands. For example, you can use arrow keys to finish the search with the following mappings:

You can disable 'anchorfind' option to match a pattern at an arbitrary position in the filename instead of the beginning. You can set the number of keys to match using 'findlen' option. If you set this value to zero, then the the keys are read until there is only a single match. Default values of these two options are set to jump to the first file with the given initial.
