Removal of the current directory (".") from @INC in Perl 5.26.0

[cah]

I ran into an issue and found starting version 5.26.0, the current directory (".") had been removed from @INC.

All files in require line assuming current directory being included in @INC will fail.

This line will fail because it assumes current directory is included in @INV:

require ".mysql/dbh"; --> FAILED

Adding "./" in front will work:

require "./.mysql/dbh"; --> WORKED
