bug#26412: 26.0.50; Minibuffer completion for "C-h f" probes unrelated stuff |
|

It seems minibuffer completion, via its subroutine
help--load-prefixes, is too eager to probe unrelated stuff, for some
reason. Here's one example:
emacs -Q
C-h f default-font-height RET
Observe in the echo area the message "No MH variant found on the
system" (also logged in "*Messages*") before the doc string of
default-font-height is shown and the usual "Type C-x 1 to delete the
help window." message is displayed in the echo area. (If you do have
MH installed, the message will state its variant instead.)
Recompiling all the *.el files doesn't help.
Why would minibuffer completion of a symbol want to know whether I
have MH installed??
As another example, why would the same "C-h f" command need to know
what kind of movemail program I have? But it does, see the second
backtrace below, obtained by setting a breakpoint at call-process and
repeating the same recipe above.
I see this both on MS-Windows (details below) and on GNU/Linux, with
today's master branch.
Here's the backtrace from the call to Fmessage:
