History
Mahmoud Al-Qudsi 0866653a87 Merge branch 'no_percent' 
Drops the % notation for process expansion. The existing notation was a
mess and expanded jobs, process ids, and process names via dark magic.
With this change, % is no longer a special character and can be used
unescaped with impunity.

The variables %self and %last, referring to fish's own pid and the pid
of the last backgrounded job respectively, have been replaced with $pid
and $last_pid. These are read-only variables, protected against being
redefined by the user.

Author's note: I would have personally preferred $fish_pid instead of
$pid but since we debated changing $version to $fish_version and then
reverted that change (with much acrimony), it makes no sense to break
with that precedent here. Additionally, $fish_last_pid is quite wordy.

Closes #4230. Closes #1202.
