No.  As stated in the specification:

  To allow a + to be the first character of a match, or a - to be the last
  character of a match, a / (forward slash) escapes the character immediately
  following (but not a newline or the terminating null character) just as a \
  (backslash) escapes a following \ or " in a C string.  ...

Thus ./str matches .str, not ./str, in the input.
