Here's a one-line patch to fix a regression in the new from_char code
I introduced into 8.4.

Versions <= 8.3 skipped over any whitespace immediately preceding any
integer field, and this behaviour was lost in HEAD when my from_char
patch was committed back in September '08 [1].

Fortunately, since the code has been refactored, this now only needs
to be repaired in one place =)

With thanks to Jeremy Ford for sending in his bug report, and an
abject mea culpa.

Cheers,
BJ
