# This git extension converts a chromium commit number to its git commit hash.
# It accepts the following input formats:
#
# $ git crrev-parse Cr-Commit-Position: refs/heads/master@{#311769}
# $ git crrev-parse ' Cr-Commit-Position: refs/heads/master@{#311769}'
# $ git crrev-parse 'Cr-Commit-Position: refs/heads/master@{#311769}'
# $ git crrev-parse refs/heads/master@{#311769}
#
# It also works for branches (assuming you have branches in your local
# checkout):
#
# $ git crrev-parse refs/branch-heads/2278@{#2}
#
# If you don't specify a branch, refs/heads/master is assumed:
#
# $ git crrev-parse @{#311769}
# $ git crrev-parse 311769
# Developer note: this script makes heavy use of prefix/suffix/pattern
# substitution for bash variables. Refer to the "Parameter Expansion"
# section of the man page for bash.
