[AUCTeX-devel] Strange behaviour

[Angelo Graziosi]

I use Emacs-23+AUCTeX latest CVS and I see the following strange
behaviour, at least in my opinion.

Suppose that in my TeX doc (.tex) I have

... $e^{+}$...

and that I have to change the '+' (plus) sign with the '-' (minus). Then
I select[*] '+' and type '-', but I got

... $e^{+-}$...

and not ... $e^{-}$... I have to delete the extra '+' manually.

This happens only with the '-' (minus) character. If I type any other
character it works fine, i.e. selecting the '+' and typing 'a' or 'b'
or... whatever, I got (correctly)

... $e^{a}$... or ... $e^{b}$... or...

Another example: if in the word 'verbatim' I would change any character
(say the 'i') with the '-' (minus) then selecting 'i' and typing '-'
produces 'verbati-m' and not 'verbat-m'.

The above happens only with AUCTeX. If I write .F, .txt, .c, .cxx etc.,
the examples given work just fine.

Cheers,
   Angelo.
