mercurial branch name use integer as a name

问题：
mercurial branch name use integer as a name

解决：

到安装目录下找到mercurial/scmutil.py文件（我的：/usr/local/Cellar/mercurial/3.8.1/lib/python2.7/site-packages/mercurial），修改下面

def checknewlabel(repo, lbl, kind):
# Do not use the "kind" parameter in ui output.
# It makes strings difficult to translate.
if lbl in ['tip', '.', 'null']:
raise error.Abort(_("the name '%s' is reserved") % lbl)
for c in (':', '\0', '\n', '\r'):
if c in lbl:
raise error.Abort(_("%r cannot be used in a name") % c)
//这里以前没有注释掉，现在注释掉，这样就不会对名称进行int检查，就可以使用
//int 类型的名字了
# try:
# int(lbl)
# raise error.Abort(_("cannot use an integer as a name"))
# except ValueError:
# pass
