Sorry for the incompatibility with other platforms.
However, I will not change the present behaviors
on windows.

PS:
If example-image-a.pdf is in the current directory,
or in a directory for which there is not ls-R,
kpsewhich example-image-A.pdf
probably returns
./example-image-A.pdf
or
/somedir/example-image-A.pdf
on case-insensitive Mac.
Sorry if I am wrong.

Thanks,
Akira
