Since commit r15098

Looks like just a linefeed issue probably. What's odd is my commit should have broken things and strk's fixed, but seems to be other way around. Mine didn't trigger a failure but his did.

[strk]

Editorconfig must have removed trailing spaces that should have been instead expected, comping from:

    elog(ERROR,                                                                 
        "AddToPROJ4SRSCache: could not parse proj4 string '%s' %s",             
        proj_str, pj_errstr);  

Looks like pj_errstr would be empty when given an proj_str...

yah I'm fixing now.

[strk]

In 15101:

Re-add accidentally removed trailing spaces in an _expected file

Also tweak .editorconfig to avoid this accident in the future

Fixes #3630
