getPatchedFiles in oe.patch doesn't correctly handle filenames with spaces

[Alberto Pianon <alberto@pianon.eu>]

Hi All,

by using Tinfoil together with methods found in oe.* to do software 
composition analysis, I encountered an error: when parsing python3 
recipe, I found patch file 
[0001-gh-92036-Fix-gc_fini_untrack-GH-92037.patch](https://git.yoctoproject.org/poky/tree/meta/recipes-devtools/python/python3/0001-gh-92036-Fix-gc_fini_untrack-GH-92037.patch?h=kirkstone) 
which refers to a filename with spaces:

+++ b/Misc/NEWS.d/next/Core and 
Builtins/2022-04-28-23-37-30.gh-issue-92036.GZJAC9.rst

when using function oe.recipeutils.get_recipe_patched_files(d), the file 
above is returned as "b/Misc/NEWS.d/next/Core", missing the whole part 
after the space.

The problem lies in [function 
patchedpath]((https://git.yoctoproject.org/poky/tree/meta/lib/oe/patch.py?h=kirkstone#n126) 
within the static method getPatchedFiles in poky/meta/lib/oe/patch.py, 
which assumes that there are no spaces in filenames

filepth = patchline.split()[1]

Even if spaces in filenames are bad practice, my understanding is that 
they are allowed by git diff and should be supported.

To solve this issue, the above line may be modified as follows

filepth = patchline[4:]

Should I submit a patch for that?

Regards,

Alberto
