Fibonacci program lengths

Python 2, 160 bytes

s='s=%s;c=s;l=len(s%%c)+4;a,b=1,1\nwhile b<l:a,b=b,a+b\nc+="1"*(b-l-1);print s%%`c`;a=1'
c=s
l=len(s%c)+4
a,b=1,1
while b<l:a,b=b,a+b
c+="1"*(b-l-1)
print s%`c`

This is a true quasi-quine; it doesn't read its own source, but it generates it. First output (has trailing newline):

s='s=%s;c=s;l=len(s%%c)+4;a,b=1,1\nwhile b<l:a,b=b,a+b\nc+="1"*(b-l-1);print s%%`c`;a=111111111111111111111111111111111111111111111111111111111111111111111';c=s;l=len(s%c)+4;a,b=1,1
while b<l:a,b=b,a+b
c+="1"*(b-l-1);print s%`c`;a=1

Second:

s='s=%s;c=s;l=len(s%%c)+4;a,b=1,1\nwhile b<l:a,b=b,a+b\nc+="1"*(b-l-1);print s%%`c`;a=1111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111';c=s;l=len(s%c)+4;a,b=1,1
while b<l:a,b=b,a+b
c+="1"*(b-l-1);print s%`c`;a=111111111111111111111111111111111111111111111111111111111111111111111

_{Edit: Oops. Forgot to change the string when I changed from ;s to 1s, so the second output was outputting extra semicolons (which Python doesn't support). Fixed}

Python - 89

g="%(s,b,a+b);print o.ljust(b-1)";s,a,b="s,a,b=%r,%i,%i;o=s%"+g,89,144;exec("o=s"+g)#####

My perfect character count is gone. ;_; Thanks to TheRare for pointing out the newline thing and Quincunx for suggesting I use Python 2, shaving off 2 chars.

EDIT: Now just uses more #s instead of 1s; 12 chars shorter.

EDIT 2: 94 chars! Eliminated some repetition. >:3

EDIT 3: Shorter repr alternative for Python 2.

EDIT 4: Output is a character shorter now.

EDIT 5: The use of %r to shorten it was taken from an answer on another question by @primo.

EDIT 6: Shorter. :D

Here's a Python 3 version:

g="%(s,b,a+b);print(o.ljust(b-1))";s,a,b="s,a,b=%r,%i,%i;o=s%"+g,89,144;exec("o=s"+g)####

This answer is similar to the one by @Quincunx.
