Hi Alex and sorry for the late reply.
The main use case is a more readable `.clang-tidy` configuration checks.
Before this correction one can use something like this:
---
Checks: '
,*,
,-cert-dcl03-c,
'
...
It works, but is hardly comprehensible to a newbie (the strange use of
addtional commas).
Since the spaces are ignored (since a recent commit of yours) we can remove the
leading comma and hope that no user uses a tab...
After applying this patch, we can just write (with tabs or spaces and as many
newlines as we want - used for grouping for instance):
---
Checks: '
*,
-cert-dcl03-c,
'
...
Additionaly, you can sometimes accidentally issue a tabulator on the command
line and that's just nice to ignore it.
