Fix partial matching issues in tests

[MichaelChirico]

One complication is the changes to R/splom.R. Basically we have a contradiction between the package source and what's tested:

lattice/tests/test.R

Line 91 in f216545

pscales = list(list(at = 6, lab = "six", limits = c(-10, 10)),

In effect, under partial matching, any pscales entry with a name starting with lim is accepted, but any user with strict matching rules must supply lim.

If the intention truly is to let the user supply any ^lim.* list item, that should be better encoded in the sources (and perhaps documented); this PR assumes the test is in error instead to avoid back-compatibility issues.

Details

To reproduce:

setwd('tests')
pmatchRe = "partial( argument)? match"
writeLines(con=".Rprofile", c(
  "options(warnPartialMatchArgs=TRUE, warnPartialMatchAttr=TRUE, warnPartialMatchDollar=TRUE)",
  sprintf("globalCallingHandlers(warning=function(c) if (grepl('%s', conditionMessage(c))) stop(c) else warning(c))", pmatchRe)
))

tests = list.files(pattern='[.][rR]$', full.names=TRUE)
for (t in tests) local({
  system2("R", c("CMD", "BATCH", t))
  tmp = paste0(basename(t), "out")
  on.exit(unlink(tmp))
  l = grep(pmatchRe, readLines(tmp), value=TRUE)
  if (length(l)) message(t, "\n", l)
})

unlink(".Rprofile")

Thanks. Would you mind filing an issue about the lim vs limits thing? I would like to fix it eventually, when I feel brave enough to do a revdep check.
