--args does not function as expected

[fritzr]

Description

When running gdbgui --args .... one would expect to be able to paste the program arguments following the --args option, as with gdb. However it appears that gdbgui attempts to interpret options following --args as options to gdbgui itself instead of the inferior to debug, contrary to the text in gdbgui --help.

Steps to replicate

$ gdbgui --args `which gcc` -c test.c -o test.o
usage: gdbgui [-h] [--args ARGS [ARGS ...]] [-x GDB_CMD_FILE] [-g GDB] [--rr]
              [-p PORT] [--host HOST] [-r] [--auth-file AUTH_FILE]
              [--user USER] [--password PASSWORD] [--key KEY] [--cert CERT]
              [--license LICENSE] [--project PROJECT] [-v]
              [--hide_gdbgui_upgrades] [-n] [--debug]
              [cmd [cmd ...]]
gdbgui: error: unrecognized arguments: -c -o test.o

It looks like gdbgui --args "cmd args..." (with quotes around the full program string, including flags and arguments) does work. However, this is not how it is described in the usage string:

usage: gdbgui [-h] [--args ARGS [ARGS ...]] [-x GDB_CMD_FILE] [-g GDB] [--rr]
              [-p PORT] [--host HOST] [-r] [--auth-file AUTH_FILE]
              [--user USER] [--password PASSWORD] [--key KEY] [--cert CERT]
              [--license LICENSE] [--project PROJECT] [-v]
              [--hide_gdbgui_upgrades] [-n] [--debug]
              [cmd [cmd ...]]

Recommend updating the usage text to show quotes around --args "ARGS...".
