Re: [bug #39943] Add an alternative parsing mode that regards space and tab as identical tokens

[Tim Murphy]

The detection also appears to only work if the statement has a syntax
error in it.

e.g.
fred:
        X=25;echo$$X


With 8 spaces the above is not warned about even though to the human
eye when you use vim's search function to highlight spaces it becomes
visually highly suspicious.

1) it's immediately after a target or
2) immediately after a recipe
3) it's indented which is an odd thing to do outside of any context such as ifeq

I'm not suggesting that there's any truly satisfactory way to be sure
of this but even if an "info" message appeared or an "NB" or if one
had to switch on some special warning mode that was extra picky -
whatever it was would be handy and perhaps discourage people from
using styles that could end up in confusion.  50 years down the line
for gmake 5 our children might then switch from notification to
warning and finally enforcement of something.


Regards,

Tim
