"j" is now an ambiguous command

[Jan Engelhardt]

Between gdb-7.3 and 7.4.50.20120603, gdb has gained the two commands 
"jit-reader-load" and "jit-reader-unload".
This causes "j", previously used as a shortcut for "jump", to have 
become ambiguous. I would ask for "j" to be recognized again, similar to 
how "b" is synonymous with "break" despite the presence of other b* 
commands.

  (gdb) j 1762
Ambiguous command "j 1762": jit-reader-load, jit-reader-unload, jump.

thanks,
Jan
