PeptideMapper does not report peptide hits, but protein hits #69

Description

@cbielow

given:

a peptide.csv as

DKEKEK
EKEKEK

and a protein.fasta (expected hit in second line) as

>sp|Q95283|COX41_PIG Cytochrome c oxidase subunit 4 isoform 1, mitochondrial (Fragment) OS=Sus scrofa OX=9823 GN=COX4I1 PE=2 SV=1
MLATRVFNLIGRRAISTSVCVRAHGSXVKSEDYALPVYVDRRDYPLPDVAHVKNLSASQKA
XKEKEK
ASWSSLSMDEKVELYRLKFNESFAEMNRST

the result of PeptideMapper is:

XKEKEK,Q95283,62

The position is correct, but PeptideMapper does not tell how many peptides were matched to this position (here it's 2).
To perform this mapping, one needs external tools, which is a bit inconvenient.

I would hope to see a result like:

EKEKEK,Q95283,62
DKEKEK,Q95283,62

which would tell me the actual peptide sequence(s) matched
