This is certainly a confusing inconsistency in Thunderbird if not an
out-right bug (depends on whether this way of wrapping long character
strings is actually an approved Email standard).
RFC 822 requires support for up to 999.
Format-flowed says that long lines are split with each line ending in
=20CR. Each split line should be no longer than 80 characters
(including the =20CR). Your input meets this format.
The =20CR is removed and the next line is concatenated until a line
does NOT end with =20CR. At that point you have the original long
input line. This requires that the receiving MUA support
Format-flowed however.
Apparently some other

other hand there are certainly Email clients that send long URLs without
using this formatting convention, as I frequently receive long URLs in
Emails (including the reformatted version of this URL from Paul) that
work fine with Thunderbird.
See my prior message. The URL was malformed since it was not included
in angle brackets. URLs without angle brackets are part of the text
and are not indicated as URLs - Thus may not be spotted for special
treatment. Note that such text URLs MAY be correctly handled anyway
but you are playing Russian Roulette with 5 bullets if you do not
bracket your URLs.
