Work with absolute paths

[krlmlr]

Work around rstudio/rmarkdown#1889.

Is there a reason not to use normalizePath() here? I'd prefer to keep the dependencies lighter.

[krlmlr]

The file must exist, this is generally not true for out_path:

normalizePath("bogus")
#> Warning in normalizePath("bogus"): path[1]="bogus": No such file or directory
#> [1] "bogus"

^{Created on 2020-09-03 by the reprex package (v0.3.0)}

Same with mustWork = FALSE sans warning.

We can work around if you think it's worth it, or copy code from fs.

I guess the other option is to require/document that the user supply absolute paths? That might be easier given that I expect relatively few people to be calling this function.

[krlmlr]

Works now. Do we need a test?

[hadley]

Yeah, a test would be useful I think.

[krlmlr]

Done.

Resolved conflicts.

I bumped into this issue today and, although rstudio/rmarkdown#1889 has been closed, I suspect it is not truly fixed. Anecdotally, it feels like rmarkdown::pandoc_convert(output =) only works below session temp dir.

I am having trouble using downlit_md_path(out_path = ) when out_path is not below session tempdir. I intend to follow-up with a better reprex and issue here or in rmarkdown, but in case I don't, I wanted to at least note that there still seem to be path problems as of 2022-08-16.
