[PATCH] Really fix git-merge-one-file-script this time.
The merge-cache program was updated to pass executable bits when
calling git-merge-one-file-script, but the called script
supplied as an example were not using them carefully.
This patch fixes the following problems in the script:
* When a new file is created in a directory, which is a file in
the work tree, it tried to create leading directory but did
not check for failure from the "mkdir -p" command.
* The script did not check the exit status from the
git-update-cache command at all.
* The parameter "$4" to the script is a file name that can
contain almost any characters, so it must be quoted with
double quotes and also needs to be preceded with -- to mark
it as a non-option when passed to certain commands.
* The chmod command was used with parameter "$6" or "$7" to set
the mode bits. This contradicts with the strategy taken by
checkout-cache, where we honor user's umask and force only
the executable bits. With this patch, it creates a new file
by redirecting into it (thus honoring user's default umask),
and then uses "chmod +x" if we want the resulting file
executable. Without this fix, the merge result becomes 0644
or 0755 for users whose umask is 002 for whom it should
become 0664 or 0775.
* When "$1 -> $2 -> $3" case was not handled, the script did
not say which path it was working on, which was not so useful
when used with the -a option of git-merge-cache.
