SZEDER Gábor efaa0c1532 bash prompt: combine 'git rev-parse' executions in the main code path There are a couple of '$(git rev-parse --<opt>)' command substitutions in __git_ps1() and three of them are executed in the main code path: - the first to get the path to the .git directory ('--git-dir'), - the second to check whether we're inside the .git directory ('--is-inside-git-dir'), - and the last, depending on the results of the second, either * to check whether it's a bare repo ('--is-bare-repository'), or * to check whether inside a work tree ('--is-inside-work-tree'). Naturally, this imposes the overhead of fork()ing three subshells and fork()+exec()ing three git commands. Combine these four 'git rev-parse' queries into a single one and use bash parameter expansions to parse the combined output, i.e. to separate the path to the .git directory from the true/false of '--is-inside-git-dir', etc. This way we can eliminate two of the three subshells and git commands.
