In order to support more user-friendly command list file,
this commit adds the support for:
+ comment lines: line staring by '#' are ignored
+ escaped enf-of-line: line with trailing ' \' are continued
on next one
For eol: we impose a space before the '\' in order not to trigger
the escape if the '\' is for example at the end of a value in a
'key=value' sequence.
Althought it does not have any real interest in interactive mode,
the prompt is adapted when in that case.
