* Clarified meaning of indentchar setting
The description "sets the indentation character" combined with the default value of a space led me to believe that this was a way to set a preference for tabs/spaces and choose a number of spaces per indentation all at once. I've updated the description to try to make its true function clearer.
* Added note on rmtrailingws
This behavior was unexpected for me, so it's probably good to let other users know which option has precedence.
* Added details to help command
Initially I kept trying to use `help <command-name>` rather than `help commands`
The old notation (for example `CtrlG`) causes confusion when combined
with new notation needed for alt (`Alt-g`) due to Alt being case
sensitive. Previously both formats were supported, but the documentation
and defaults used a combination. This commit only uses the new notation
for consistency.
Ref #1470
* Adds command "tabmove ±n", for better tab management
* Added tabmove to help:commands
* Replace uses of util.Min, util.Max with util.Clamp
Browsing code and discovered `util.Clamp`, ideal for this section of my code
* oops, missed an arg
* Typo, again
The -l flag to the replace command means "literal" and will treat
the search term literally instead of as a regular expression.
The command bar also now supports expanding environment variables
and running expressions through the shell and using the result
in the command.
