Fix malformed payload when bundeling multiple commits

[tabakhase]

reference to #24 as #27 is not fixing it (using gitweb)
resolves the greedy regex to produce ","short":false}]},&&&&&Tabakhase","value":

(using negative look-around would be cleaner, but does not seem to work there)

[init-js]

that patch doesn't fix the issue either. negating [^;]* does prevent the .* from being greedy, but then any ';' in the preceding field will cause the group to be shorter than it should.

[tabakhase]

Im also not super happy with [^;]* but the best possible (negative look-around didnt work).
Chances of having a ; in the commiters name is quite low tho (but for sure possible)
