imap-send: cleanup execl() call to use NULL sentinel instead of 0
Some versions of gcc check that calls to the exec() family have the proper sentinel for variadic calls. This should be (char *) NULL according to the man page. Although for all other purposes the 0 is equivalent, gcc nevertheless does emit a warning for 0 and not for NULL. This also makes the usage consistent throughout git. The whitespace in function calls throughout imap-send.c has its own style, so I left it that way. Signed-off-by: Junio C Hamano <junkio@cox.net>
