Editor do Mercurial: “abort: o sistema não consegue encontrar o arquivo especificado”

Tenho um problema em fazer com que o Mercurial reconheça meu editor. Eu tenho um arquivoc:\windows\notepad.exe e digitar "bloco de notas" no prompt de comando funciona. Eu posso confirmar usando o "-m"argumento para fornecer o título do commit. Mas um simples"hg commit"traz o erro.

Uma chamada para "hg --traceback commit" traz à tona:

Traceback (most recent call last):

Eu tentei definir a variável de ambiente HGEDITOR, definindo "visual ="e"editor =" noMercurial.ini Arquivo. Eu tentei o caminho completo e apenas o comando. Eu também tentei copiar o arquivo notepad.exe na pasta atual e na pasta mercurial.

Idealmente, eu gostaria de usar o editor neste local "C:\PortableApps\Notepad++Portable\Notepad++Portable.exe", mas nesta fase eu ficaria feliz com qualquer editor!

Saída do debugconfig do HG:

c:\wamp\www\SiteAB.com\web>hg debugconfig
