Subject: add: make pathless 'add [-u|-A]' warning a file-global function
X-Git-Tag: v1.8.3-rc0~45^2~4
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/e24afab09137d785f07e62aee8936b548436d21f?hp=7bf7a92f69f8b0af7169af390e53397698fcfa95

add: make pathless 'add [-u|-A]' warning a file-global function

Currently warn_pathless_add() is only called directly by cmd_add(),
but that is about to change.  Move its definition higher in the file
and pass the "--update" or "--all" option name used in its message
through globals instead of function arguments to make it easier to
call without passing values that will not change through the call
chain.
