Previously the `autocmd` to replace the date on the first line if `Last
change: ` was present resulted in the cursor being moved in non `help`
filetypes due to the substitution failing. Now the substitution is only
attempted if the current file is a `help` file.
Add `autocmd` to automatically expand the `_template` snippet on the
`BufNewFile` event, if the expansion fails because the `_template`
snippet does not exist for the current `filetype` undo the changes. Do
the same thing when the `filetype` changes to `help`, since these are
`text` files to begin with the first `autocmd` has no effect.
* `todo`, `note` now do not add comment strings when in a comment line
* `fixme` added to match `todo` and `note
* `date` renamed `datetime` and updated to match the unix `date` command
* `date`, `time` added inserting only the date or time now
* `utc` updated, no longer spitting the timezone offset
Based on [AnsiEsc.vim](https://github.com/vim-scripts/AnsiEsc.vim)
separate out the syntax highlighting into a separate `ansi` filetype.
This conceals escape sequences and highlights ansi color escape
sequences in text files so that they have the same appearance as in the
terminal.
The oblitum fork of YouCompleteMe is getting dated and uses LLVM 4.0 on
macOS, this results in erroneous errors in the system headers on macOS
since it's not been updated to match upstream. Use Valloric's repo to
avoid these errors on macOS.
