---------------------------------------------------------------------- (0006156) mirabilos (reporter) - 2023-02-18 20:33 https://austingroupbugs.net/view.php?id=1630#c6156 ---------------------------------------------------------------------- I honestly don’t remember any more :| The last mention of this is from March 2020: | allow ‘+’ in alias names (just not as first character, like ‘-’) mksh’s getopt has + and - as flag starters both, hence handling them the same. The last change of “valid characters in alias names” before that was in April 2017 (: and [ but not exactly "[[")… and shortly before, - was re-added but not as first character (after we had stripped the list down to what POSIX said at that time). That was shortly before that, and I *think* it was done in response to some user or researcher (Stéphane Chazelas is good at doing so) finding some issue with allowing “too much” in alias names. So, sorry, I don’t recall details after five years. I do appreciate the note asking applications not to do it; I’d appreciate it even more if an alias name beginning with [+-] could have implementation-specified behaviour (so I could continue rejecting them) but I understand if you’re reluctant to do so on the vague amount of reason I can give.
