Comment 1 for bug 1995728

I think I understand the reason for the buggy line break.
The wrap() documentation says: "When words that are longer than $columns are encountered, they are broken up."
But there are spaces where the line could be broken. Why are they not used?
Because the part "epicsShareExtern reg_func " is the $initial_tab and thus not considered for line break. After that, "pvar_func_register_func_abcdefghijklmnopqrstuvwxyz0123456789" has no space, thus it is broken up.

The solution is:
$Text::Wrap::huge = "overflow";
