Allow . character as part of command names.

Browse Source 
This patch adds . as an allowed character for user defined commands.
Combined with 'define-prefix', this allows to e.g. define a set of Valgrind
specific user command corresponding to the Valgrind monitor commands
(such as check_memory, v.info, v.set, ...).
