A #! line in these files is misleading, since these scriptlets are meant to be sourced with '.' (using whatever shell sources them) instead of run directly using the interpreter named on the #! line. Removing the #! line shouldn't hurt syntax highlighting since these files have filenames ending with '.sh'. For documentation, add a brief description of how the files are meant to be used in place of the shebang line.

# Helper functions used by interactive rebase tests.
|
|
|
|
# After setting the fake editor with this function, you can
|
|
#
|
|
# - override the commit message with $FAKE_COMMIT_MESSAGE
|
|
# - amend the commit message with $FAKE_COMMIT_AMEND
|
|
# - check that non-commit messages have a certain line count with $EXPECT_COUNT
|
|
# - check the commit count in the commit message header with $EXPECT_HEADER_COUNT
|
|
# - rewrite a rebase -i script as directed by $FAKE_LINES.
|
|
# $FAKE_LINES consists of a sequence of words separated by spaces.
|
|
# The following word combinations are possible:
|
|
#
|
|
# "<lineno>" -- add a "pick" line with the SHA1 taken from the
|
|
# specified line.
|
|
#
|
|
# "<cmd> <lineno>" -- add a line with the specified command
|
|
# ("squash", "fixup", "edit", or "reword") and the SHA1 taken
|
|
# from the specified line.
|
|
#
|
|
# "exec_cmd_with_args" -- add an "exec cmd with args" line.
|
|
#
|
|
# "#" -- Add a comment line.
|
|
#
|
|
# ">" -- Add a blank line.
