Public bug reported:

In EPICS 7, when processing a dbd file with a long function name (> 24
chars), registerRecordDeviceDriver.pl generates buggy output.

With the following file test.dbd:
function(abcdefghijklmnopqrstuvwxyz0123456789)

The command perl registerRecordDeviceDriver.pl test.dbd generates code with a line break in the middle of a variable name:
epicsShareExtern reg_func pvar_func_register_func_abcdefghijklmnopqrstuvwx
    yz0123456789;

I suspect the error is in line 191 caused by the usage of wrap().

I have tested this with perl v5.16.3 and v5.26.3.
