Oh ... after a bit more experimentation, there's an easier way.
Apparently the real problem is that Solaris' sed doesn't handle
[[:alpha:]] (I wonder if this is locale-dependent?). I get
correct results after expanding it manually, eg
tgl@gcc-solaris11:~$ echo except foo, bar: | sed -e 's/except \([a-z][a-z.]*\), *\([a-z][a-zA-Z]*\):/except \1 as
\2:/g'
except foo as bar:
We aren't likely to need anything beyond a-zA-Z and maybe 0-9,
so I'll go fix it that way.
