tcsh users sometimes alias the 'git' command to another name. In
this case, the user expects to only have to issue a new 'complete'
command using the alias name.
However, the tcsh script currently uses the command typed by the
user to call the appropriate function in git-completion.bash, either
_git() or _gitk(). When using an alias, this technique no longer
works.
This change specifies the real name of the command (either 'git' or
'gitk') as a parameter to the script handling tcsh completion. This
allows the user to use any alias for the 'git' or 'gitk' commands,
while still getting completion to work.
A check for the presence of ${HOME}/.git-completion.bash is also
added to help the user make use of the script properly.

#
|

# 1) Copy both this file and the bash completion script to ${HOME}.
|
|
# You _must_ use the name ${HOME}/.git-completion.bash for the
|
|
# bash script.
|
|
# (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash).
|
|
# 2) Add the following line to your .tcshrc/.cshrc:
|
|
# source ~/.git-completion.tcsh
|
|
|
|
set __git_tcsh_completion_original_script = ${HOME}/.git-completion.bash
|
|
set __git_tcsh_completion_script = ${HOME}/.git-completion.tcsh.bash

# Check that the user put the script in the right place
