# Set the name of the end-user facing command in the reflog when the
# script may update refs.  When GIT_REFLOG_ACTION is already set, this
# will not overwrite it, so that a scripted Porcelain (e.g. &quot;git
# rebase&quot;) can set it to its own name (e.g. &quot;rebase&quot;) and then call
# another scripted Porcelain (e.g. &quot;git am&quot;) and a call to this
# function in the latter will keep the name of the end-user facing
# program (e.g. &quot;rebase&quot;) in GIT_REFLOG_ACTION, ensuring whatever it
# does will be record as actions done as part of the end-user facing
# operation (e.g. &quot;rebase&quot;).
#
# NOTE NOTE NOTE: consequently, after assigning a specific message to
# GIT_REFLOG_ACTION when calling a &quot;git&quot; command to record a custom
# reflog message, do not leave that custom value in GIT_REFLOG_ACTION,
# after you are done.  Other callers of &quot;git&quot; commands that rely on
# writing the default &quot;program name&quot; in reflog expect the variable to
# contain the value set by this function.
#
# To use a custom reflog message, do either one of these three:
#
# (a) use a single-shot export form:
#     GIT_REFLOG_ACTION=&quot;$GIT_REFLOG_ACTION: preparing frotz&quot; \
#         git command-that-updates-a-ref
#
# (b) save the original away and restore:
#     SAVED_ACTION=$GIT_REFLOG_ACTION
#     GIT_REFLOG_ACTION=&quot;$GIT_REFLOG_ACTION: preparing frotz&quot;
#     git command-that-updates-a-ref
#     GIT_REFLOG_ACITON=$SAVED_ACTION
#
# (c) assign the variable in a subshell:
#     (
#         GIT_REFLOG_ACTION=&quot;$GIT_REFLOG_ACTION: preparing frotz&quot;
#         git command-that-updates-a-ref
