The derep_fulllength command fails to remove the part of the header after the space

[torognes]

The derep_fulllength command fails to remove the part of the header after the space.

The part of the header line from the first space should be ignored (unless the --notrunclabels option is in effect). This does not seem to apply to the derep_fulllength command, but it should.

vsearch \
    --derep_fulllength <(printf ">header metadata\nA\n") \
    --minseqlength 1 \
    --sizeout \
    --quiet \
    --output -

gives:

>header metadata;size=1
A

instead of:

>header;size=1
A

I've written about a hundred tests for the dereplication-rereplication functions, but I have to admit I did not test the header parsing.

[frederic-mahe]

I've added two new tests for that specific issue (frederic-mahe/vsearch-tests@620cd91).

The bug was introduced in version 2.8.2, but is fixed in version 2.8.6 just released.

PASS: derep_fulllength: header stops at first space (issue 338)
PASS: derep_fulllength: notrunclabels includes full header (issue 338)

Perfect :-)
