bug#37526: 27.0.50; double-recording of keys with input-methods and keyboard-macros

[Christoph Arenz]

There are still some cases where keyboard macros do not record correctly
for some input-methods, leading to double-recording of keys.

I tried some simple tests using the french word for brother (`frère' --
the first `e' is with a ``' on top of it -- hopefully my mailer does not
screw this up...)
using various french input methods: french-prefix, french-postfix and
french-azerty -- all in context of keyboard macro recording and playback.
Here are the results:

french-prefix:
keys pressed: <f3> f r ` e r e , <spc> <f4> <f4> <f4>
text inserted in buffer: "frère, frère,  frère,  "
last-kbd-macro: "fr`ere,  "
--> Note the two(!) <spc> recorded after the `,' though only one was
typed in!

french-postfix:
keys pressed: <f3> f r e ` r e , <spc> <f4> <f4> <f4>
text inserted in buffer: "frère, frèrre,, frèrre,, "
last-kbd-macro: "fre`rre,, "
--> Note the double recording of `r' and `,' !

french-azerty:
keys pressed (on US keyboard-layout): <f3> f r e 7 r e m <spc> <f4> <f4>
<f4>
text inserted in buffer: "frère, frère, frère, "
last-kbd-macro: "fr7rem "
--> This looks as I would expect it.

A quick check on emacs-24.5.1 on Ubuntu showed that all cases were
handled correctly back then.
N.B. For what it's worth, I am physically using a german keyboard with a
US layout in GNOME.
Probably this should not matter and be equivalent to a US keyboard...

Thanks for your attention,
Christoph
