bash: refactor searching for subcommands on the command line
This patch adds the __git_find_subcommand function, which takes one argument: a string containing all subcommands separated by spaces. The function searches through the command line whether a subcommand is already present. The first found subcommand will be printed to standard output. This enables us to remove code duplications from completion functions for commands having subcommands. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
