Bug#586549: mktexlsr does not fail on intermittent errors

[karl@freefriends.org (Karl Berry)]

Well, I definitely do not want to add set -e to our fundamental scripts
a week before our final release.  But if you want to add it for Debian,
I don't know of any specific reason not to.  You can experience the
pain, or lack thereof.

As I've written before:
- I am not a fan of set -e in general, because
  I've seen too much otherwise-unnecessary code added to placate it, and
  confusing silent aborts result.
- but I do not categorically refuse to add it in the future. 
- After the release.

    Do you know of any reason why set -e was
    not used from the very begining?

I don't know of any specific technical reason.  I expect Thomas was no
fan of set -e either.
