Subject: [PATCH v2 04/11] t/lib-rebase: change the implementation of commands with options

From: Charvi Mendiratta <[email-masked]>
Date: Tue, 9 Feb 2021 00:55:22 +0530

"fixup" and "merge" mirrors the implementation of FAKE_LINES handling of
"exec", but the cases are quite different. The argument to "exec" is
arbitrary and can have any number of spaces embedded in it, which
conflicts with the meaning of spaces in FAKE_LINES, which separate the
individual commands in FAKE_LINES. Consequently, "_" was chosen as a
placeholder in "exec" to mean "space".

However, "fixup" is very different from "exec". Its arguments are not
arbitrary at all, so there isn't a good reason to mirror the choice of
"_" to represent a space, which leads to rather unsightly tokens such
as "fixup_-C". Let's replace it with simpler tokens such as "fixup-C"
and "fixup-c".
