Fixes #5623.

Sourcing oh-my-zsh happens in zshrc, which will override settings of

Changing from `zcat` to `zgrep` because some `zcat` implementations do not work
if the file is not compressed.

Currently, only tasks with complete subproject specifier are added to
.gradletasknamecache. Gradle commands can be called for all (sub-)projects
they are defined for, using their name as defined in the subproject, here
called "simple" task names. One example is "gradle clean".

This patch adds support for parsing out those "simple" task names from the list
of fully specified task names. The .gradletasknamecache file will contain
both the fully specified names, and the "simple" names for your autocompletion
pleasure.

Closes #5683

Although `gaa` (git add --all) is cool, it stages every file, tracked or
not, if it is not on .gitignore.

Sometimes we want to just stage everything we are working on, that is
already tracked. For that reason, 'gau' can save us some time.

if a variable is passed and is valid - will play the playlist
if a variable is passed and is invalid(no such playlist) - will stop all playing

The whitespace in line 13 creates a double whitespace when combined with line 24. Therefore 2 whitespaces appear between ${user_host} and ${current_dir}.
