PBM image decoding regression since 3.0.2

Description

Some recent changes since 3.0.2 seems to have broken decoding for certain PBM images.

The PBM image in question is very simple. Here is its full content:

P1
6 10
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
1 0 0 0 1 0
0 1 1 1 0 0
0 0 0 0 0 0
0 0 0 0 0 0

It is also attached as in.pbm.

On latest git master (d693392), it can't be decoded:

Same thing happens for the 3.1 release.

On the other hand, the 3.0.2 release decodes it just fine:
