This is not how GNU programs should behave.  The GNU coding standards 
explicitly say

 Avoid arbitrary limits on the length or number of _any_ data structure,
 including file names, lines, files, and symbols, by allocating all data
 structures dynamically.  In most Unix utilities, "long lines are
 silently truncated".  This is not acceptable in a GNU utility.

So everything that is subject to user input must be malloced in libltdl, 
and strlcpy will only be used to *protect against programmer mistakes*. 
 Which means, abort if they are found, instead of "silently truncated".
