>Description:
src/lib/libalias/alias_ftp.c checks only for uppercase P,O,R,T and E,P,R,T when modifying commands during active ftp sessions.

>How-To-Repeat:
Use a ftp client that sends lowercase commands (e.g. konqueror) in active mode.
>Fix:
if changing 'if (ch == 'P')...' to 'if (ch | 0x20 == 'p')...' is considered ok I can supply patches.
