Width and precision restrictions are not captured exactly the same as format() generates in some situations

[purpleskyfall]

Some inconsistence occured when parse the follow string:

>>> import parse
>>> pattern = ' {:4} {:2} {:4} {:1} {:12.3f}'
>>> line1 = ' SUWN  A    1 P -3062023.278'
>>> line2 = ' URUM  A    1 P   193030.186'
>>> parse.parse(pattern, line1) # correct
<Result ('SUWN', ' A', '   1', 'P', -3062023.278) {}>
>>> parse.parse(pattern, line2) # incorrect
<Result ('URUM', 'A ', ' 1 P', ' ', 193030.186) {}>

This one is quite tricky, since the width stuff is really hard to get right when constructing the regex internally. I think there's going to need to be some tricky re-plumbing of the way I handle width and precision of string and number parsing to make your case work :(
