Broken push with Newline in title

[muschellij2]

PR goal: fix newline

This is a smaller PR than #493 which has fixed the paths issue. This may be fixed as I've opened issue with r-lib/gh#92. Other than whitespace, the main fix is simple gsub on \n.

Here would be a reprex but the non-interactive choices need to be made with ui_yeah, so I'll use the example r-lib/gh#92 to show that it's an issue.

library(usethis)
pkgpath <- file.path(tempdir(), "testpkg")
create_package(pkgpath, open = FALSE) # creates package below temp directory
proj_set(pkgpath)

dfile = proj_path("DESCRIPTION")
desc = desc::desc(file = dfile)
desc$set("Title" = "I Want a Newline\n In My Title")
desc$write(file = dfile)
desc$get("Title")


## now, working inside "testpkg", initialize git repository
use_git()

## create github repository and configure as git remote
use_github(protocol = "https") ## to use https

Typo/Whitespace

Also, slight fix with spacing on template.R, where reprex is (before fix):

usethis::use_template("blah")
#> Error: Could not find template 'blah'in package 'usethis'.

and

usethis::use_template("blah")
#> Error: Could not find template 'blah' in package 'usethis'.

after fix.

This still seems to include a bunch of unrelated changes which makes it hard to review.
