test-http-bad-server: refactor the reading logic to avoid early return
Our ultimate goal is to add another way to define the connection needs to be
closed. To do so, we need the "read" code to be more unified.
Differential Revision: https://phab.mercurial-scm.org/D12045
This test tries to exercise the ssh functionality with a dummy script
creating 'remote' repo
$ hg init remote
$ cd remote
$ echo this > foo
$ echo this > fooO
$ hg ci -A -m "init" foo fooO
insert a closed branch (issue4428)
$ hg up null
0 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg branch closed
marked working directory as branch closed
(branches are permanent and global, did you want a bookmark?)

$ hg ci --close-branch -mc1
$ hg up -q default

Make sure hg is really paranoid in serve --stdio mode. It used to be
possible to get a debugger REPL by specifying a repo named --debugger.
$ hg -R --debugger serve --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', '--debugger', 'serve', '--stdio']
[255]
$ hg -R --config=ui.debugger=yes serve --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio']
[255]
Abbreviations of 'serve' also don't work, to avoid shenanigans.
$ hg -R narf serv --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio']
[255]
#else
rhg aborts early on -R without a repository at that path
$ hg -R --debugger serve --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', '--debugger', 'serve', '--stdio'] (missing-correct-output !)
abort: repository --debugger not found (known-bad-output !)
[255]
$ hg -R --config=ui.debugger=yes serve --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', '--config=ui.debugger=yes', 'serve', '--stdio'] (missing-correct-output !)
abort: repository --config=ui.debugger=yes not found (known-bad-output !)

$ hg -R narf serv --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio'] (missing-correct-output !)
abort: repository narf not found (known-bad-output !)
[255]
If the repo does exist, rhg finds an unsupported command and falls back to Python
which still does the right thing
$ hg init narf
$ hg -R narf serv --stdio
abort: potentially unsafe serve --stdio invocation: ['-R', 'narf', 'serv', '--stdio']
