Re: [Bug-readline] Completing A=<TAB> doubles the A

[Дилян Палаузов]

Hello Chet,

this is then not readline, but bash specific:

$ gdb
(gdb) !ls
'A=B'  'A=B.C'
(gdb) exec A=<TAB>

comeletes to A=B, whereas
(gdb) exec A\=<TAB>

does not complete.

Where is the = documented and why is it possible for gdb to bahave intuitively, 
but not for bash?

Regards
  Дилян
