By default, there is no special processing of backslash characters in
backquote-delimited strings.  This makes such strings useful for
regular expressions.  If a backquote-delimited string is given the Q
suffix, then backslash processing will take place.  You can see this
using slsh:

  slsh> `one\ntwo\nthree\n`;
  one\ntwo\nthree\n
  slsh> `one\ntwo\nthree\n`Q;
  one
  two
  three

Note that if a backquote character is to be included in a backquote-delimited
string, then it must be doubled:

  slsh> `One backquote: ```;
  One backquote: `
  slsh> `Two backquotes: `````;
  Two backquotes: ``

I hope this helps.
Thanks,
