Cau,

patch uz vypada lip, ale porad mi ho nejde aplikovat, ale zas tak to
nevadi - viz nize. Rekl bych, ze problemy bude delat gmail, pres ktery
to asi posilas. Ten tvuj patch ma spatne konce radku. Mrkni se prosim na
http://thread.gmane.org/gmane.comp.version-control.git/139190 a zkus si
to nastavit jak tam pisou. Pak zkus poslat patch sam sobe, ulozit si
cely email do souboru a patch zpatky naaplikovat prikazem

  git am < ulozeny.patch

Kdyz to udelas a bude to fungovat, tak taky zjistis, ze predmet emailu
se stane nazvem commitu a telo mailu bude text commitu, takze posilat
mail s predmetem "LPC21ISP regenerated patch" a zadnym doplnujicim
textem neni uplne dobry napad.

Vyzkousel jsem to a mas pravdu. Nahravani se soucasnym lpc21isp mi
nefunguje. Naaplikoval jsem tvuj patch rucne, ale nefunguje to ani s
tvoji zmenou, takze zatim nic aplikovat nebudu. Je potreba, aby nekdo
zjistil, v cem je vlasne problem a udelal opravu podle toho.
