match: fix root calculation for combining regexps with simple paths
The fall-back root for walking is the repo root, not no root.
The "roots" do however also end up in m.files() which is used in various ways,
for instance to indicate whether matches are exact. The change could thus have
other impacts.
# bash completion for the Mercurial distributed SCM -*- sh -*-
# Docs:
#
# If you source this file from your .bashrc, bash should be able to
# complete a command line that uses hg with all the available commands
# and options and sometimes even arguments.
#
# Mercurial allows you to define additional commands through extensions.
# Bash should be able to automatically figure out the name of these new
# commands and their options. See below for how to define _hg_opt_foo
# and _hg_cmd_foo functions to fine-tune the completion for option and
# non-option arguments, respectively.
#
#
# Notes about completion for specific commands:
#
# - the completion function for the email command from the patchbomb
# extension will try to call _hg_emails to get a list of e-mail
# addresses. It's up to the user to define this function. For
# example, put the addresses of the lists that you usually patchbomb
# in ~/.patchbomb-to and the addresses that you usually use to send
# the patchbombs in ~/.patchbomb-from and use something like this:
#
# _hg_emails()
# {
# if [ -r ~/.patchbomb-$1 ]; then
# cat ~/.patchbomb-$1
# fi
# }
#
#
# Writing completion functions for additional commands:
#
# If it exists, the function _hg_cmd_foo will be called without
# arguments to generate the completion candidates for the hg command
# "foo". If the command receives some arguments that aren't options
# even though they start with a "-", you can define a function called
# _hg_opt_foo to generate the completion candidates. If _hg_opt_foo
# doesn't return 0, regular completion for options is attempted.
#
# In addition to the regular completion variables provided by bash,
# the following variables are also set:
# - $hg - the hg program being used (e.g. /usr/bin/hg)
# - $cmd - the name of the hg command being completed
# - $cmd_index - the index of $cmd in $COMP_WORDS
# - $cur - the current argument being completed
# - $prev - the argument before $cur
# - $global_args - "|"-separated list of global options that accept
# an argument (e.g. '--cwd|-R|--repository')
# - $canonical - 1 if we canonicalized $cmd before calling the function
# 0 otherwise
