Spaces for Punjabi affixes

Spaces are mostly separated by words, but some single words are typically spelled with spaces in the middle of them in Gurmukhi. The words ਕਰ ਕੇ and ਕਰਕੇ are always pronounced exactly the same way but ਕਰ ਕੇ is a verb form and ਕਰਕੇ is a postposition. ਕੇ is an inseparable affix that may have been a separate word some centuries ago, but that you cannot insert anything between it and that it is invariant/uninflecting is a sure sign that it is not a separate word where it occurs in contemporary writing. Shahmukhi writers represent both as کرکے.

Is it ok to break a line between the stem and the affix? Or should content authors use a non-breaking space? Should the gap be the width of a normal space?

It would be nice to have a couple of examples with meanings and IPA transcriptions attached.
