OK, let me ask more specific questions:

  1. Why was the amount of whitespace in the tags table different from
     that in the source file?
  2. What command(s) was/were used to produce the tags table?
  3. Why are the issue and you talking about "trailing whitespace",
     while the difference between Expected and Actual in the issue is
     in leading whitespace, not trailing whitespace?

etags.el doesn't understand any languages, that is the job of the
program that produces the tags table.  etags.el just follows the rules
for the format of tags in the tags table.  I don't know about trailing
whitespace, but tags for HTML files surely include embedded
whitespace, for example.

So once again, I suggest to focus on the particular problem you had,
because I'd like to find a solution for that without making
backward-incompatible changes in behavior of etags.el.
