If I call for instance realgud:pdb on a on a python file that contains spaces in the name, the suggested command line to execute is similar to the following: python -m pdb /absolute/path/this\ is\ a\ test.py.

The debugger exits immediately with an error, printing the following lines:

Making font-lock-breakpoint-keywords buffer-local while locally let-bound!
using pdb mode map
Making kill-buffer-hook buffer-local while locally let-bound!
That’s all folks.... exited abnormally with code 1

The debugger starts correctly if I manually change the suggested line adding quotes this way: python -m pdb "/absolute/path/is a test.py"

Is there a way to change the default suggestion so that I don't have to manually change it every time?
